Actually it gets a bit more complicated. You're also likely sharing resources like ethernet connections, and still somewhat succeptible to what others are doing.
I also think that media intensive pages aren't going to be where you encounter issues when it comes to drupal. It's more likely going to be related to the requirements of the construction of the page.
One rather extreme example is a client who has seemingly fairly simple requirements and not a huge traffic load but certain elements on the page - for example drop-down menus for the entire site - cause a massive amount of database queries (1100/page) to load each page. Block caching (menus don't change often) and other techniques have reduced this number and helped, but because of the way drupal works it's still a heavy site - and that's with few images and next to no media. It's heavy on the database, a major shared resource.
In short, there's really no way to say that all sites with a certain set of requirements will work with a given solution. I never thought the site I'm speaking of would have these issues (granted it was my first drupal project and i had a lot to learn about the architecture at that point).
In general, drupal is a pretty hoggy system - if you have experience building java/jsp sites, spec your server out similarly to that. If you spec it like you would other php apps you'll probably be disappointed.

I'm trying to decide between dedicated hosting and a VPS setup. Make sure I understand this correctly. In both cases, you can control your mysql connections, and you get all of them, so that won't change. The thing that changes between a VPS and a dedicated server is the amount of RAM and CPU that you are given, right?
Having said that, for a site that isn't media intensive (mostly flat page), how am I to gauge how much RAM/CPU I need, especially when the numbers for expected visitors is obviously throwing a dart at a board? Is there any general rule of thumb for how many page views/users/hits translates into xxx RAM/CPU requirements?
I understand this is a almost ridiculous question, as it is difficult to pinpoint something like this, but am I able to expect hundreds of users on a VPS? Thousands? 20? Any direction would be greatly appreciated.
